Evaluation of fractionally distilled Picea abies TMP-turpentine on wood-decaying fungi: in vitro, microcosm and field experiments

Chemical fungicides are often harmful to people and the environment because of their toxicity. The wood protection industry places a high priority on replacing them with natural products. Therefore, this investigation focused on developing a formulation of a binary combination of Salvia rosmarinus Spenn and Cedrus atlantica Manetti obtained by Simultaneous hydrodistillation to protect the wood from decay using a mixture design methodology. The chemical composition of essential oil was identified by gas chromatography coupled with mass spectrometry (GC/MS), and their anti-wood-decay fungal activity was assessed using the macrodilution method against four fungi responsible for wood decay: Coniophora puteana, Coriolus versicolor, Gloeophyllum trabeum, and Poria placenta. The results of GC/MS identified myrtenal as a new component appearing in all binary combinations. The optimum anti-wood-decay fungal activity was observed in a combination of 60% S. rosmarinus and 40% C. atlantica essential oils, providing an effective concentration for 50% of maximal effect (EC50) value of 9.91 ± 1.91 and 9.28 ± 1.55 μg/mL for C. puteana and C. versicolor, respectively. The highest anti-wood-decay fungal activity for G. trabeum and P. placenta was found in the combination of 55% of S. rosmarinus and 45% of C. atlantica essential oils, with EC50 values of 11.48 ± 3.73 and 22.619 ± 3.79 μg/mL, respectively. Combined simultaneous hydrodistillation improved the antifungal effect of these essential oils. These results could be used to improve antifungal activity and protect wood against wood-decay fungi.

This paper develops chicken feather protein-based wood preservatives (CFP-WP). The treatability, leachability and chemical structure of the CFP-WP were analyzed. The crystallinity, thermal properties, micromorphology and decay resistance against fungi of the treated wood samples were investigated to examine their efficacy. The production cost of CFP-WP was also assessed. The results showed that CFP-WP (Cu, B and small molecular amino acids) was able to penetrate into wood cell walls and the active ingredients of preservatives interacted with wood constituents were well fixed onto wood blocks, evidenced by SEM–EDS observation, NMR, FTIR, XRD and TGA/DTG analysis. The morphology analysis elucidated that CFP-WP effectively protected wood against decay fungi. Decay experiments verified that the new preservative prolonged the wood service life, reducing the mass loss up to 10.88% from 51.02% compared to the untreated wood. Further, the production cost of CFP-WP (approx. 130–140 €/tonne) is nearly 30% lower than the commercial price of conventional market preservatives, such as ACQ (approx. 210 €/tonne). The excellent functionalities of this CFP-WP eco-friendly formulation present a great potential to be used as an environmentally benign wood preservative.
